Does anyone have experience with Gree ducted heatpumps and their internet connectability?

Friends can't get the device connected to the cloud service and the installer suggests their ISP replace their router. I've tried different routers and no go even with the settings pared down as suggested in the app 11gn WPA2 only etc.

The app fails on trying to connect the device to the Gree cloud service. The device hotspot is active, I've tried moving the router closer, moving the device wifi module, etc.

Any thoughts? Does it use an antenna in the wifi module or the antenna on the big white box? I've got to the point it must be an incompatibility between the Gree app and the wifi module.

The hand held unit will have its own wifi, so would need to be in proximity of their router. ~~However, it may be disabled if it's connected to the larger unit.~~

Have you tried finding an APK of an older version of the app?

Have you tried connecting the hand held unit directly to the heat pump, in case the larger unit is at fault?

Edit: looks like the larger unit only has RF, for a remote, so you're relying on the smaller one.

I can't help with this. I had no end of trouble with my Panasonic ducted unit, including WiFi. The WiFi adapter in the heat pump turned out to be faulty in my case. In the end the whole Panasonic ducted unit was removed, it was really not good in many ways.

I have normal Gree heat pump in my cabin.
The only way I could get it to connect to the wifi was making a separate SSID that’s only on 2.4ghz.

Opinions are my own and not the views of my employer.

Ahh yes, there is 1 wired remote (plugged into the pictured white box) and 2 wireless remotes, I hadn't thought about the white aerial being for them.

Not sure which hand held unit you are referring to but putting the WiFi adaptor into setup mode via the wired controller works as it should, the hotspot becomes active. It's when the app is searching for it to add it to Gcloud that app reports a failure.

Older version of the app could be a go . . .

Thanks, I have tried that.

Sorry, meant the eudemon adapter in your hand. They should be able to be plugged directly into the heat pump, instead of the unit it appears to be connected to in the roof space. But if it's going into setup mode correctly, it probably won't achieve anything to go direct to the heat pump.

Have you tried setting it up on a different ISP, in case it's not the device at fault? The app may need to phone home before it connects to the wifi adapter.

Could it be that it works on a wifi channel not officially supported in NZ, i.e channel 14 or similar?

Other issue I had was with my Panasonic wifi modules where I needed to set them up with another router that supported WPS, then part way through the install, swap routers back again to finish the setup.

Have had odd issues with various non mainstream IoT devices... You'd think by now these things would just work.

It's a ducted heatpump so the air handling unit is in the roof space right next to that white box which is presumably the brains of the whole system.

2nd point is probably on the money, they've been talking to an after sales support guy who said they have had an issue with 2degrees in the past requiring 2degrees to take action to resolve. That has me thinking it is CGNAT stopping the Gree cloud talking to the local device. My Daikin is smart enough to work around that, I'm picking their Gree isn't.

The WiFi channel was one of the first things I checked, thanks.

No WPS option is apparent on this gear.

See below, probably a CGNAT related issue.

Opening up this old thread... did you manage to resolve the gree cloud vs potential CGNAT issue?

I've been trying to help connect my parents new ducted gree heatpump to their wifi but the system keeps getting stuck at the end. They're with 2degrees for internet so wondering if this is the cause...

Hi

They gave up in the end. I think the Gree person was supposed to get back to them but didn't.

I'm in Australia, with no CG-NAT, using Unifi WAP, and have the Alexa Gree skill operating our Gree Air Con.

Have you checked your neighbour's wifi signals? Are you on a crowded channel? Do your neighbours have the same SSID? (I've seen this before in NZ where the ISP supplied gateway device did not have a unique SSID and the neighbour had the same ISP and identical SSID)

On the Gree remote have you reset the WiFi? I had to do this after the air con unit lost its connection to WiFi.

Good luck.

Thanks guys, the Gree Wireless device connects to the wifi ok, just doesn't seem to communicate fully with the Gree Cloud.

I went down the following steps:

turn off all other fritzboxes
turn off 5ghz on the main router
minimise number of wireless clients present (ended up just my phone connected during setup)
reset the gree adaptor via the control panel
connect to the gree hotspot
give it the home wifi details
see the additional device on the fritz wifi clients list

Then the setup comes to a grinding hault...

Have reached out to the installer to get support from Gree but this might look like a trial static IP to see if it'll work...

So, a quick update... Tried connecting the Gree wifi adaptor to a phone hotspot, and same drill, get to 99% and then it all stops.

Lets see what Gree support will have to say...
